Excellent photographs - there must have been many, many stones taken from the site. There's supposedly a fourth Devil's Arrow (should be easier to track) which has been used to bridge a small river somewhere nearby.

Read this three times late last night, fascinating stuff.

The thing I find most interesting is Inigo Jones saying the stone had been taken to St James.

The more I look at the etching, and realising that it was done either from memory or as a third-hand story, could the two stones to the right not be construed as the present Altar stone, or possibly a bluestone almost buried beneath the top half of stone 55 ?

more on this story on local TV in the west today.
Marlborough archaeologist (probably Pitts) argued that it couldn't come from stonehenge as there is no other stone like it there now.
Naff argument as the alter stone which is still there is also one of a kind.

Much as I hope you are right on your theory with these stones, I can't help thinking that the woodcut shows a stone outside the horseshoe, possibly bluestone 36 which is still lying down, The pointed end of the stone would hint that it had fallen inwards, making it closer to the trilithon. Of course it may have been dragged out of the central area to be chopped up but my head says bluestone and a souvenir hunter rather than a quarryman. Of course, as you say, the woodcut and the stones are likely not connected, so there is every chance these stones did come from within the horseshoe. I think deep down the woodcut is a red herring :(

Roman road stones were often worn down over time leaving grooves - could there not be a grooved section on the pointed half beneath the ground that would account for the two bridges - one of each wheel, with natural wear and tear accounting for the groove?

Does anyone know why the doors in Hamish's photo's are sandbagged?

I realise that stones are marked in various ways on MAGIC, sometimes as sarsen Stones, other times just with the letter 'S', but usually marked with a round dot.

Anyone know what the 'Sl' with the dot is, at Grid Ref SU072393, 140m ENE of the two stones ?

Has anyone ever wondered how an upright stone can swivel through 90 degrees and then lay nicely down flat at right angles to the central trilithon ?

The current altar stone is in a really strange position in relation to where it was supposed to be - it appears to have jumped from its socket, twisted round 90 degrees, moved across 6 feet and then laid down perfectly at right angles, all with another stone crashing down on it. In other words, it never stood up on end.

Which leaves at least one socket to be filled...

found another one but its so covered in Lichen I can't tell if its sarsen or bluestone.

Why have they been removed from MAGIC?

They were definitely marked last week!

Or am I going mad now?
